KNOT-TIER.

To all whom it may concern:

Be it known that 1, CHARLES R. JUDGE, a citizen of the United States,residing at Chelmsford, in the county of Middlesex and Commonwealth ofMassachusetts, have invented a certain new and useful Improvement inKnot-Tiers, of which the following is a specification.

This invention relates to knot-tying devices.

The object of this invention is to provide a simple, inexpensive andeflicient device for tying together broken ends of yarns in spooling,twisting and other machines and to leave the free ends of the yarnsbeyond the knot of uniform length. The knot-tier hereinafter describedis without joints or movable parts and without cutting edges or otherportions liable to require repairs and is preferably made of a singlepiece of wire bent to form the looper or part around which the yarn islooped and the hook or part which retains the free end portions of theyarns while the loop is drawn over them. Said looper may however, bemade of cast metal and have the hook attached thereto in any convenientmanner.

The knot-tier will usually be permanently secured to the spooler ortwister, but I have also shown it provided with means for attaching itto the hand of the operator, so that it may be moved from one brokenthread to another as may be required in some cases, as in j ack-spoolingor warping cot-ton, woolen or worsted. hen permanently attached to aspooler or twister it will be convenient to have one knot-tier at everyinterval between spools or bobbins.

In the accompanying drawing, Figure 1 is a plan of the best form of myinvention; Fig. 2, a vertical transverse section of the same on the line2 9 in Fig. 1; Fig. 3, a left side elevation of the front end, showingthe operative parts of the knot-tier, with the first position of the twoyarns or ends to be united; Fig. 4:, an elevation of the knot-tierinverted, showing the second position of the yarns, also means ofattaching the same to the left hand of the operator; Fig. 5, anelevation of the parts shown in Fig. 3, the yarn being in the secondposition; Fig. 6, like Figs. 8 and 5, but showing the yarn in theSpecification of Letters Patent.

third position with the bends of the knot completed but not drawn tight;Fig. 7, a horizontal section of the hook 011 the line 7 7 in Fig. (5with completed knot drawn close; Fig. 8 like Fig. 7, except that thewaste end of the yarn is severed; Fig. 9, an end elevation of the frontside of the locker or waste-box, spindle-rail and the attaching rail, aside elevation of one of my knot-tiers attached to said rail, a spindleand a spool; Figs. 10 and 11, a plan and left side elevation,respectively of a modification of my invention.

In the cheapest and best form (Figs. 19) of my invention, one end of asingle wire is provided with an eye a and an intermediate portion ofsaid wire is provided with another eye (L1 and these eyes may befastened to an attaching rail B secured to the top of the front 0 of thewaste-box or locker G, as commonly used in a spooler, or to any othercon venient stationary part of a machine, in connection with which thedevice is to be used. I have shown these eyes arranged above and belowsaid rail B and secured thereto by a bolt 2) and nut 6 From the eye a atthe top of the rail B the wire projects horizon tally forward at a andat a runs downward and backward, to form an incline, then at a backwardto the eye a and then forward and slightly in advance of the incline (4where it is provided with a hook a the point of which extends back ofsaid incline.

In making the tier of wire it will be more convenient first to doublethe wire and to form the lower eye a at. about two-fifths of the lengthof the wire from one end thereof, then to twist the doubled wirestogether at a nearly to the end of the shorter portion leaving enough ofthe shorter portion to form the hook a which is inclined. outward fromthe body of the device, preferably to the left as one faces the device,as shown in Fig. 1, and the other portion of the wire is then bent toform the incline a and the upper horizontal port-ion of the tier, theextreme end of the said last-named portion being formed into the eye a.The looper (meaning the parts a a a) and the hook a should extendforward beyond the line of the spindles in a spooler and should be fromtwo and a half to three inches above the plane of the tops of the spoolsto allow sufficient space between the tiers and the t spool for thehands of the operatives. The incline a directs yarns pressed against itdown upon the hook (1. and into the space between said hook and thelooper.

In tying up a pair of ends, one end from a spool D and the other from abobbin (not shown) are carried together up to the left of the looper andhook by the right hand and wound once around the looper, the parts ofthe yarns between the tier and the left hand from the spool and bobbinare then thrown over the tier to the right, so that the different partsof the yarn above mentioned will occupy the positions shown in Figs. atand 5 (the tier in Fig. 4 being inverted from the position shown in Fig.3) and the free endportions of the yarn are then passed through the hooka as shown in said Figs. 4 and 5, and the yarn is drawn forward andmakes a figurc8 knot, shown in process of formation in Figs. 6 and 7 andcompleted in Fig. 8 where the free end-portions of the yarns areseparated or broken off, the yarn at both sides of the knot being drawnforward by the left hand with sufficient force, so that the yarns beingheld by the friction of its loops at one side of the wire and byfriction of the wire as shown at the right hand portion of Fig. 7,placing the index finger of the right hand as close as possible to theknot Fig. 7, then with sufficient force, the ends will break at a pointwhere the greatest strain comes, leaving the knot on the yarns connectedto the spool and bobbin and leaving the free ends of the yarnsprojecting from the knots a distance substantially equal to thecircumference of the wire at as shown in Fig. 8.

In the tier shown in Figs. 10 and 11 the looper is represented as aplate A of suitable material, as cast metal, formed in one piece with asupporting bracket a which carries a hook a the looper and hook servingthe same purpose as the hook and looper shown in the preceding figuresand above described. The bracket is fastened to any suitable support asby a screw passing a hole in said bracket.

The tier shown in Fig. 3 is provided with rings or eyes large enough toreceive the thumb of the left hand. Of course for a left-handed personthe hook might be arranged on the opposte side of the looper and thetier might be worn on the right hand. It is however, immaterial, exceptas a matter of convenience on which side of the looper the hook isplaced, if the yarns are placed properly about the looper and in thehook.

The twisting of the wires at a and the twisting of the shank of the hooka in Figs. 10 and 11, represented at a retain the yarn r on said shankand prevent the premature accidental displacement of said yarn.

I claim as my invention 1. A. knot-tying device having a looper, aroundwhich a yarn or thread may be wound, and a hook, rigidly secured to saidlooper and lying wholly outside of the plane of said looper, the pointof said hook being inclined toward said plane, to prevent said hook fromcatching in a loop being drawn from said looper and to facilitate theengagement of said hook with the free end portions of said yarn.

2. A knot-tying device having a looper, around which a yarn or threadmay be wound, a hook, rigidly secured to said looper and lying whollyoutside of the plane of said looper, the point of said hook beinginclined toward said plane, to prevent said hook from catching in a loopbeing drawn from said looper and to facilitate the engagement of saidhook with the free end portion of said yarn, and said looper beingprovided with one or more eyes which serve as attaching means for saidtying device.

A knot-tying device having a looper provided with substantially paralleledges of unequal length, an inclined front end connecting the edges ofsaid looper, a hook secured to the shorter edge of said looper, theclosed end of said hook extending for ward beyond said incline and thepoint of said hook extending back of said incline and arranged betweenthe shank of said hook and the non-adjacent edge of said looper.

l. A knot-tying device having a looper provided with substantiallyparallel edges of unequal length, an inclined front end and a hooksecured to the shorter edge of said looper, the closed end of said hookextending forward beyond said incline and the point of said hookextending back of said incline and arranged between the shank of saidhook and the non-adjacent edge of said looper and the shank of said hookbeing notched to retain yarn thereon.

A knot-tier formed of wire, having a looper comprising substantiallyparallel portions of unequal length connected at their front ends by anincline, having also a hook, the shank of which is twisted to theshorter of said parallel portions, said hook extending forward beyondsaid incline and the point of said hook extending backward beyond saidincline.
